Having issues - fuel trims. Changed all sensors no vacuum leaks only 2 codes i get. Soo suspected fuel leaky injectors. Slap on the fuel pressure tester and holding good pressure but guage is shaking like crazy within a few psi but shaky. So holding pressure but seems like regulator. Have new pump assembly but before i go for it anybody else have these issues 04 ram 5.7 hemi

If you fixed the truck, the codes should go away after you drive a few days
